There are many good reasons to study mathematics: preparation for a career, use in another field, or the beauty of the subject itself. Students at Colgate who major in mathematics go on to careers in medicine, law, or business administration as well as areas of industry and education having an orientation in science. Non-majors often require mathematical skills to carry on work in other disciplines, and all students can use the study of mathematics to assist them in forming habits of precise expression, in developing their ability to reason logically, and in learning how to deal with abstract concepts. There are also many people who view mathematics as an art form, to be studied for its own intrinsic beauty.
All mathematics courses are open to qualified students. Entering first-year students who have successfully completed at least three years of secondary school mathematics, including trigonometry, should be adequately prepared for MATH 111. Students who have studied calculus in secondary school are often ready to enter MATH 112 or 113.
MATH 111, 112 (or equivalent calculus experience approved by the department) is required for admission to a major or minor in mathematics.
The requirements for a major in mathematics are as follows:
- MATH 113 and 214 completed by the end of the sophomore year.
- MATH 250 completed by the end of the sophomore year with a grade of C or better.
- MATH 320 and 323
- Five additional mathematics courses numbered 300 or above. One of these must be a senior research experience which will normally be MATH 399 or a 400-level course. With department chair pre-approval, on occasion the research experience may be satisfied by an independent study. See “Advanced Placement and Transfer Credit” below for additional information.
Majors who are planning to undertake graduate study in mathematics are advised to take MATH 421 and 424.
Minor Program in Mathematics
The requirements for a minor are as follows:
- MATH 113 and 214.
- MATH 250 completed with a grade of C or better.
- Either MATH 320 or 323.
- Two other mathematics courses numbered 300 or above. See “Advanced Placement and Transfer Credit” below for additional information.
Minor Program in Applied Mathematics
The requirements for a minor are as follows:
- MATH 113 and 214.
- MATH 250 completed with a grade of C– or better.
- MATH 308.
- Two of the following courses: MATH 310, 311, 312, 313, 315, 316, 317, 329, MATH/BIOL 302, MATH 458 (formerly MATH 407), MATH/BIOL 481. See “Advanced Placement and Transfer Credit” below for additional information.
In order to graduate with a major in mathematics, a minor in mathematics, or a minor in applied mathematics, the student must have a GPA of at least 2.00 in mathematics courses counted for the major or minor.
The department also strongly recommends that students pursuing a major or a minor in mathematics complete COSC 101 or its equivalent.
Honors and High Honors
To qualify for honors in mathematics, majors must take, as one of the courses required for the major, a course at the 400 level. Majors must have a GPA of at least 3.30 in mathematics courses counted for the major. For high honors, the corresponding GPA must be at least 3.70. Candidates for honors must also perform satisfactorily on the honors examination, which is given once each semester and covers MATH 320 and 323.
Based upon the result of the honors examination, a student may be invited to stand for high honors. A candidate for high honors must, under the guidance of a faculty member of the department, write a high honors paper during the senior year and make an oral presentation of the results. In order for high honors to be awarded, the department must accept this paper and presentation as being of high honors quality. The high honors candidate may register for an independent study course so that the paper satisfies the senior experience requirement.
See “Honors and Awards: Mathematics” in Chapter VI.
Students should review the MATH 111, 112, and 113 course descriptions for information on topics and prerequisites, or consult with a department faculty member. In general, students are encouraged to enroll in a higher-level course. Students may drop back from MATH 112 to MATH 111 within the first three weeks, subject to available space in an acceptable MATH 111 section.
Students who have taken the Calculus-BC, Calculus-AB, or Statistics Advanced Placement exam of the College Entrance Examination Board will be granted credit according to the following policy:
- Students earning 4 or 5 on the Calculus-BC Advanced Placement exam will receive credit for MATH 111 and 112. Students earning 3 on the Calculus BC exam will receive credit only for MATH 111.
- Students earning 4 or 5 on the Calculus-AB Advanced Placement exam will receive credit for MATH 111.
- Students earning 4 or 5 on the Statistics Advanced Placement exam will receive credit for MATH 105.
- There are no other circumstances under which a student will receive credit at Colgate for a mathematics course taken in high school.
Transfer credit for a mathematics course taken at another college will be granted upon the pre-approval of the department chair. Mathematics majors or minors may not receive transfer credit for MATH 250, 320, or 323, but must pass these courses at Colgate and must take them as regularly scheduled courses, not as independent studies. At most, two transfer or independent studies courses may be counted toward a major or minor.
International Exam Transfer Credit
Transfer credit and/or placement appropriate to academic development of a student may be granted to incoming first year students who have achieved a score on an international exam (e.g., A-Levels, International Baccalaureate) that indicates a level of competence equivalent to the completion of a specific course in the department. Requests should be directed to the department chair. Any such credit may not be used to fulfill the university areas of inquiry requirement, but may count towards the major.
The Department of Educational Studies offers a teacher education program for majors in mathematics who are interested in pursuing a career in elementary or secondary school teaching. Please refer to “Educational Studies.”
Computer Science/Mathematics Major
See “Computer Science.”
Mathematical Economics Major
Mathematical Systems Biology Minor
See “Mathematical Systems Biology.”
Colgate sponsors several study-abroad programs that can support continued work toward a major in mathematics. These include, but are not limited to, the Wales Study Group (U.K.), the Australia Study Group, the Australia II Study Group, and the Manchester Study Group (U.K.). For more information about these programs, see “Off-Campus Study” in Chapter VI.
MATH courses count toward the Natural Sciences and Mathematics area of inquiry requirement, unless otherwise noted.
101 Precalculus Mathematics
A study of the following types of functions, their properties, and their graphs: polynomials, rational functions, trigonometric, exponential, and logarithmic functions. This 0.25-credit course is intended for students whose background in mathematics may be deficient. Its objective is to lay a foundation for the study of calculus and concurrent enrollment is MATH 111 is required. Credit is contingent upon completion (regardless of grade) of MATH 111. Prerequisite: permission of the instructor. Offered in the fall only.
105 Introduction to Statistics
An introduction to the basic concepts of statistics. Topics include experimental design, descriptive statistics, correlation, regression, basic probability, mean tendencies, the central limit theorem, point estimation with errors, hypothesis testing for means, proportions, paired data, and the chi-squared test for independence. Emphasis is on statistical reasoning rather than computation, although computation is done via spreadsheet. Prerequisite: three years of secondary school mathematics. Note: This course is not open to students who have either received credit for or are currently enrolled in CORE 143S, the former MATH 102, or MATH 317.
111 Calculus I

Prerequisite: three years of secondary school mathematics including trigonometry.
112 Calculus II
A continuation of the study of calculus begun in MATH 111, including the calculus of inverse trigonometric functions, techniques of integration, improper integrals, l’Hôpital’s rule and indeterminate forms, applications of integration, and Taylor series. Prerequisite: MATH 111 with a grade of C– or higher or equivalent experience in a secondary school calculus course.

Prerequisite: MATH 111 with a grade of C– or higher or equivalent experience in a secondary school calculus course.
149 Mathematical Deliberation
The emphasis throughout this course is the development of the ability to think creatively - to solve mathematical exercises that must be stated as a mathematical model (the creative thinking aspect) and then solved using techniques encountered during a student’s secondary educational experience in mathematics in the courses known as algebra, plane geometry, trigonometry and elementary functions. An inspiration for this offering reflects the ability of computers and calculators to carry out many of the mathematical techniques needed to obtain a solution to a mathematical model - it is the modeling aspect that is now the stumbling block to solving mathematically posed problems and it has always been the more difficult aspect to address when solutions to problems (especially “word” problems) are requested.

250 Number Theory and Mathematical Reasoning
E. Hart, D. Howard, D. Lantz, D. Saracino, K. Valente
Questions about the positive integers 1, 2, 3 . . . have fascinated people for thousands of years. The ancient Greeks noted the existence of right triangles with sides of integral length, corresponding to equations such as 32 + 42 = 52 and 52 + 122 = 132. Is there a way of describing all such “Pythagorean Triples”? As another example, we observe that 5 = 12 + 22, 13 = 22 + 32, 17 = 12 + 42, while none of the primes 7, 11, or 19 can be expressed as the sum of two squares. Is there a pattern? Does it continue forever? This course focuses on such equations as a means for introducing students to the spirit and methods of modern mathematics. The emphasis throughout is on developing the ability to construct logically sound mathematical arguments and communicate these arguments in writing.
